摘要:
We report some details of the FeCl3immobilized in chitin. The polymer was characterized by infrared and Mössbauer spectroscopy. Chitin modified with iron (CH-Fe) was used as a support for thin layer chromatography and column chromatography for separation of phenolic compounds. The results show that CH-Fe can be used as an alternative support for immobilized metal affinity chromatography (IMAC).

摘要:
A simple, sensitive and highly selective detection method for nalidixic acid and flumequine has been developed. A 1-μL aliquot of sample solution was spotted onto the thin-layer plate with the aid of a disposable micropipette, and after development, the plate was sprayed first with sodium borohydride and then hydrogen peroxide successively. The spots were visualized under longwave UV light. The detection limits were 30 pmol for nalidixic acid and 60 pmol for flumequine.
